Dentin dysplasia (DD) is a rare autosomal dominant disorder of dentin development, which is generally divided into two types based on the clinical and radiographic appearance of the affected dentinal tissues: Type-I (Radicular DD) and Type-II (Coronal DD). This paper reports the case of a 17-year-old female patient with both classical and atypical features of radicular DD in the permanent dentition. The present case shows clinically normal appearing crowns, localised mobility in the maxillary teeth, completely obliterated pulp chambers, widened root canals without any obliterations and the presence of multiple periapical radiolucencies. The clinical and radiographic findings observed in this present case report are different from those reported in the past literature, which suggests that the present case could be a variation of radicular DD.

Dentinogenesis Imperfecta and dentin dysplasia are genetic oral diseases inherited in a simple autosomal dominant mode, with high penetrance and a low mutation rate. Both of them are present with bulbous crowns, marked cervical constrictions, severe attritions, few periapical radiolucencies, and premature tooth loss. The diagnosis is based on family history, and detailed clinical examination, while genetic diagnosis may become useful in the future once sufficient disease-causing mutations have been discovered. Here, we present a case with overlapping features of both dentinogenesis imperfecta and dentin dysplasia asserting both the anomalies to be part of the same continuum of the genetic event.

Amelogenesis imperfecta is a hereditary disorder with diverse clinical presentation, where enamel is the tissue that is primarily affected either quantitatively or qualitatively. Hypomaturation/hypoplastic amelogenesis imperfecta with taurodontism is a rare variant of amelogenesis imperfecta which is often confused with trichodentoosseous syndrome. We report a rare case of hereditary enamel defect with taurodontism associated with interradicular dentin dysplasia.
